You'll confront Grievous and some of his Bodyguards almost immediately. Take out the bodyguards in the way and then Force-throw a movable object at Grievous. The hearts in his health meter should turn from silver to red, which is your cue to quickly attack him with your lightsaber. After a few hits, a cut scene will trigger and you'll be taken captive in part because of the irresistibility of coffee.

As Anakin and Adi Gallia, ascend the ramp in the background and continue until your path is blocked by red and blue force fields. To destroy the blue force field, you'll have to blow up three orbs in quick succession. To begin, head to the left side and cut open the panel behind the Jedi insignia. Destroy the orb inside of it and then quickly head to the right and destroy both orbs there (throw your lightsaber for the higher one). If you do this fast enough, you'll be able to advance.

When you enter the next room, you'll have another force field blocking you, which means you have three more orbs to destroy. Start at the left again and Force the large object onto the purple panel next to it. Next, head to the two orbs on the right. You'll notice one is guarded by a golden gate. Use the Force to grab one of the Super Battle Droids and aim his fire at that gate to destroy it. Finally, hit all three orbs like before and you'll be able to pass through.

When you enter the next room you'll find a room full of enemy droids and a console that needs a droid-head to interact with. Destroy everything and then go attack the blue droid in the back of the room. Pick up its head, put it on, and then interact with the console in the center of the room.

Next, you'll switch over to Master Kenobi. Grievous, his Bodyguards, and a handful of droids will stage an assault your position, so be prepared to fight. Destroy the irrelevant droids and then use the Force to toss any of the movable objects in the room at Grievous. When his silver hearts turn red, attack him with your lightsaber. Repeat this process until he retreats.

Follow him into the hall and he'll advance on you with his four lightsabers. Retreat into the open room behind you and begin the next phase of your battle from there. Besting him will involve, you guessed it, throwing objects at him. However, this time, instead of attacking him with your lightsaber when he's stunned, pick him up with the Force and throw him. After three hits, he'll retreat once more. Cut open the door and follow him.

Adi Gallia will join you in the next phase of your duel with Grievous. As Grievous attacks Obi-Wan, switch over to Adi and attack him from behind. After he's damaged, he'll go berserk and spin around, so back off. He'll then try to attack Adi, so switch back over to Obi-Wan and attack him once more. Repeat this until Grievous (what an idiot) makes his exit.

Next, switch over to Anakin in his ship and land on the red cross in front of you. Move up the stud trail and use your lightsaber on the light blue part of the wall. Use the Force to blow away the wall and cut open the next wall you see. Cut the cables inside and switch over to Obi-Wan.

Some platforms are now available to assist you in your climb. First, use the Force to create a platform out of the blocks on the ground for you to jump on. Then, jump up until you see a hanging yellow rectangle on the right. Use your lightsaber or blaster to attack it, and a platform should fall down for you to jump on.

Climb up to the top and into the next area, using trampolines when necessary (hold the Jump Button). Fight your way through the hallway as you follow General Grievous. He'll eventually escape into a ship, which will trigger a cut scene.

Next, make your way down the hall until you see the blue insignia that practically yells for you to interact with it. Slash the console inside to open the door to your right. After entering the next area, head to the rear right side of the room and destroy the three blocks next to the contraption with red lights. Then, manipulate the pieces with the Force to create a console to interact with. Pull the switch and you'll activate some proton torpedoes for Anakin to use.

Hold the Change Character Button to switch over to Anakin. Then, head back to your ship and pick up some of those proton torpedoes. There are four pink panels to destroy, so hop to it.

After the shield covering the landing bay is gone, head over there and land to help evac your comrades. Sorry about that coffee, Agen.
